Be it known that 1, CHARLES citizen of the United ,States, residing at Verona, in the county of f Allegheny 5 State of Pennsylvania, have invented-a IIGW T and useful Improvementi in' Antic'ifeeping Devices for Railway Bails, ofwhich the-fol-f lowing is a full, clear, and exact description ,T he present invention relatesbroadlylto rail' fastenings or frail anchors and m re; articularly to fastenings o-f jthe type usual-f l referred to inthe'art as'anticreepersifon' preventing 4 longitudinal creeping of j the y rails to which they are applied;

theflatwise bend for forming the loop 4 is so made that the key abutting shoulder 5 ex;

This places the bodyiof the anti-creeper under tension, tending to bend the same, but due to the disposition of 9 its mass, it will be apparent that'a naxim'umstrength against such bending action isinsured.

In both of these forms'of the. invention, the key is formed with teeth 7 tending to prevent the key from. Working loose under the hammering action of the wheels on the track. I

The advantages of the present invention arise from theprovision of an anti-creeper whieh may be .easilyfand inexpensively ,manufactured' and in which an inclined key abutting shoulder is formed by bendin'gfa portion of the body of the anti-Creeper," whereby when the key is driven into position. distortion of the anti-creeper is prevented andfa laterally and upwardly movement thereof insured.
